Assessment rationale/justification
Within the United Arab Emirates, the species occurs throughout the Hajar Mountains. The species is listed as Least Concern in view of its presumed large and stable population, wide distribution range within the Hajar Mountains, limited threats, adaptability to habitat modification and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. This taxon is not a non-breeding visitor, and it is presumed that any immigration from populations outside the UAE is not significant, and therefore there is no adjustment to the Category according to the IUCN regional and national Guidelines (IUCN 2012).
